How to Choose Defoamer for Wastewater Treatment: Chemi Tech's Efficient Solutions

Excessive foam in wastewater treatment is a common yet critical issue, leading to reduced efficiency, higher energy consumption, and potential secondary pollution. Operators often struggle with short-lasting suppression, unstable effects, or high costs.  

Chemi Tech addresses these challenges with tailored defoamers through a structured approach:  

1. Problem Analysis: Identify foam causes (e.g., microbial activity, chemical reactions, or mechanical agitation).  

2. Product Selection: Recommend models based on water characteristics (e.g., pH, temperature, organic load). For acidic environments, KM-8102  series is ideal, while KM-8101 suits high-temperature conditions.  

3. Precise Dosing: Use automated systems to control dosage and avoid overuse.  

4. Performance Validation: Monitor foam height and turbidity to ensure long-term stability.  

A case involved an industrial park where foam overflow in a bioreactor reduced treatment efficiency by 30%. After applying Chemi Tech’s KM-8101 defoamer, foam dissipated within 15 minutes, with a 40% reduction in ongoing usage and no impact on microbial activity. This demonstrates how targeted selection optimizes cost and effectiveness.  

Chemi Tech’s defoamers leverage modified silicone polymer technology for broad compatibility across units like aeration tanks and settlers. We recommend pilot tests for model optimization and offer full technical support.
